' To all whom it may camera: p Be it known that I, AnnBEw'TR'dMBLEE, ofGlens Falls, in the county of Warrenand State of New York} have inventedcertain new and useful'lmprovementsin .Feeding Devicesfor'Sulfur-Burners; and I do herebydeclare that the followin is a full,clear, and

exact descri tion thereo which will enable rarily displaced whenrequired. 1 p

Figure ,1 shows anend view. of a rotary sulfur burner with presentimprovementapplied. Fig.2 is {a side view of the feedingapparatusinconnection with a small section 0 the b 1rner.-'v Fig-3 is aplan view of the Fig. 4 'isa secparts to the left qfth Section .i eShown in elevation. 1

Referring to the reference letter sand figures in amore particulardescri tion; 5 is the 4 rotary burner body which is o an elongatedcylindricalf-formfin the main and provided with a conical end 5.;This'burner is mounted for'rotation on rollers 6, ;6 provided on 'shafts7, 7 in the usualmannen 'f p f l The feeding device consists of ahopper'ZS supported on a stand 9 preferably from the floor, and having atubular extension providinga melting reservoir 8 extending into theopening 10 of the rotatable burner. The

hopper is provided with a circular head or flange 11 adapted to closetheopening in the end of the burner which flange at suitable intervalsis provided with inlet draft openings and on the outer faceof the flangellis pro- VidedQ' rotatable ring 12 having snnilar openings and servingasa gate for regulatin the draft openings. -In the bottornof the oper'8,which is of a genr'al 'V-shape. in 1ts -5 0 ower portion, is arranged ,ascrew or spiral conveyer 14. p This conveyer at its inner end is suported in a bracket 15 and-at its outer end as a bearing inthewall thehopper. The conveyor is driven by asprocket chain.

; l l l re erence inarked -.thereon,-

device for sulfur burners 15 running on sprocket wheels 16 and 17 andarranged on the end of the-conveyer shaft and on the prolonged end ofone of the shafts 7.- The relative sizeof the'sprocket wheels 16'and 17may be changed to secure the desired: speed for the conveyer in itsoperation. The inner-end'of the tubular extension 8 is preferably closedby a cap 18 having a re-' duced. opening 7' UNITED strA Es PATENToFFIo-E;

* ANDREW rRoMBLEnoF at 19' through which the" molten sulfur deliveredinto the burner.

To enable the hop er extension-W to be in troduced through t e opening10'or removed therefrorru'the stand 9 is provided with the] jointedsection-Q attached directly at its upper end to the hopper and pivotallyjointed to the head 9 of the stand bya bolt. 20. Provision is made for aswinging motion on the bolt 20 as a pivot by providing the slotted oening 21 in which the securing bolt 22 is aced. When the -bcrlt 22 isloosened the .opper with its QXlJGIlSlOILIIlfiY be iGIltGdtO bring thehopper extension into a substan-' tially horizontal position. workingdownwar der to adjust the height Of'ill'l hopper and itstubularextension, and more particularly the positionof the plate 11 thestand 9 is made adjustable by providing apiece 9 with a verase of thestand passes the bolt tical slotted oppning as shown at 23 through ifwhich and the In ite -0min position 1t will be arranged on a incline asshown in Fig. 2. v In or--- 24'. When this bolt is loosened the stand"can be adjusted vertically and s'e'cured at' any desired. positionwithin the limits of the 'slot 23.

In operation thec 'burner 5'will,-" of course; be rotated and inconnection therewith the conveyer 14-will'be rotated. A quantity ofsulfur will be introduced into the-hopper 8 i and gradually moved by theconveyer 14 into the reservoir 8*. The heat from the burning sulfur inthe burner will-melt the sulfur in the reservoir and the same will bedischarged ina more or less fluid state through the opening 19 intotheburner or retort. The hopper 8 will referably be kept full or wellreplenishe with sulfur, which acts as a seal for the opening through thehopper into the retort and: on this account the draft through the openins a in the plate 11 and ring 12 ca; be 'nicey adjusted to therequirements for pro er oxidation. I

arious modifications and changes inand from the. construction hereindescribed may the character described of a hopper, a meltvo1r,-substantially asset forth.

be made Without departing from thespirit of by Letters Patent is:

my invention as particularly pointed out in the claims. 1 What I'claimas new and desire to secure 1. ,"The combination in a feeding device ofing reservoir extended from the hopper ifito the burner and means in thebottom of they hopper to move the contents into the reser- 3. .Thecombination in a feedingdevice of the character described of a hopper, atubular inclined melting reservoir, a conveyer in the hopper, a closingplate for the opening in the burner all mounted on a stand forcooperation with a rotary sulfur burner, substantially as set forth.

4. "the combination in a feeding device of the'eharacter described of ahopper, an angularly arranged reservoir extension adapted tobe projectedinto the burner, an angularly adjustable stand on which the hopper andextension are mounted and a conveyor in the hopper for moviiw thecontents into the extension, substantially as set forth.

In-Witness whereof, I have affixed my signature, in presence of twowitnesses, this .28
